I can't comment on whether children are happy there - I very much hope they are. But I do agree about the physical touch part. For me there is a need to physically touch and hug my children, and I remember as I child really having that need, and would go and sit on my mother's lap sometimes even in my early teens.... and whilst matrons etc can be pleasant and kind, they cannot answer that 'physical craving' for affection.
In terms of judging - I have to say, being honest, that in our generation, where we are more emotionally attuned, I do judge the parents.
For me, it's hard to get around the idea that those parents, except for exceptional situations like serious illness in the family, are intrinsically being selfish and are choosing convenience and an easy life for themselves.
The big reason to go to boarding school seems to be the ability to do activities in the evenings, and that this basically outweighs the loss of family bonding time in the evenings. But a child at home can also do lots of activities, that is not the preserve of boarding school. However, it is far easier on the parents to delegate all the collecting, ferrying around, the care of a child in the evenings, taking them to all the activities, supervising homework etc, cooking dinner than to do it oneself.
For a parent, life is much easier when you have the freedom and flexibility to work late when required, have your evenings to yourself or to enjoy social engagements etc, and do not have to rush out of work, spend your evening driving around, or nagging about homework / tidying their room etc.
So the parents then 'strongly encourage' their child to want to go to boarding school, how amazing it is etc - and the child conveniently then wants to go.... and the parents then present it as being very much driven by the child.
I am not saying every case is like this, but many are.
And if the parents are going to prioritise their comfort/convenience/career above their child's, then yes, the child is better off at boarding school. But if they didn't it wouldn't.
I saw this happen with my neighbours recently. Only child, parents both partners at big London accountancy firms - never home before 8pm, if not later... so the girl was spending all her evenings with a nanny. In her case, yes, boarding school is better. But if one of the parents were to prioritise the child, I think you can have the same advantages (if not better in terms of the activities- as you can actually select the music or sports teachers for your child's after school activities, instead of them just having whatever the school happens to offer at that particular time), as well as regular family time.
But thank you for starting this thread OP, it's a really interesting topic, and interesting to be able to say what I really think, rather than smiling and nodding away politely when someone tells me that 'my DP can't wait to go to boarding school' :).
I have 3 DC and I do think my oldest DS would have been (outwardly at least) fine at boarding school from an extremely young age, as he was rather unemotional , independent and just got on with things. But I do wonder if whilst functioning absolutely fine, he wouldn't have missed developing some sort of emotional depth.... which he may or may not need later in life, I don't know.
